Firefox 16 was released earlier this week, but now it looks like Mozilla's latest version of its web browser was launched a little bit too early. Mozilla has confirmed that it has pulled Firefox 16 from its official download sites due to a security issue that has been discovered.
In a post on the company's security blog, Mozilla says:
The vulnerability could allow a malicious site to potentially determine which websites users have visited and have access to the URL or URL parameters. At this time we have no indication that this vulnerability is currently being exploited in the wild.
Mozilla added that it is working on an update for people who have already downloaded and installed Firefox 16 and will release that new version sometime later on Thursday. Just in case users of Firefox 16 don't want to wait for the update, Mozilla has also set up a way for those web browser users to downgrade their version back down to Firefox 15.0.1 while they wait for the new version of Firefox 16.
Mozilla recently offered a public alpha version of Firefox 18 for download, which include support for the "Modern" user interface in Windows 8.
